On a side note, I don't think I have ever seen 2 age verifiers at a single game at the same time to witness an act of drug use and report it

I have. And if they really want to get their panties in a twist it's up to the host or you. If you don't like the fact that it's going on or feel that it's extremely unsafe, notify the host that it shouldn't be going on, or worst case scenario. LEAVE!

You have the ultimate control over yourself. That's IT! You can only look after number one, it's your life, it's your lungs, etc etc.

Everyone needs to get off their high horse about this issue. I'm not saying it's good or bad. Because that's not my place. It's a personal choice for the people that partake in the activity. If they want to run the risk of potentially hurting themselves or worse-someone else-it's on them.
